ADJUSTABLE SHORE.

To all whom it may concern Be it known that I, GEORGE BROWN, a citizen of the United States, residing at Chicago, in the county of Cook'and State of Illinois, have invented a certain new and useful Improvement in Adjustable Shores, of which the following is a specification.

My shore is designed to be used for concrete or false flooring.

Devices of this kind at the present time, are generally formed of timbers, Wl'llCh have been sawed off to accommodate the varying heights of the different floors of the different buildings, which results in the loss of a great many thousands of feet of waste lumber, which is an increasing expense due to the increasing cost of material. Attempts have been made to remedy this by designing ad-.

justable shores, but those of which I am familiar, the construction has been so expensive as to practically prohibit their manufacture commercially.

My invention has for its object to provide an adjustable shore which will serve for various heights and to providea simple and inexpensive form of construction, and at the same time to provide a construction which will be as rigid and satisfactory as the shore formerly employed for this purpose, and

has for its further object to provide a construction in which all of the pieces are secured to each other so that none of the operative parts can be lost in transferring the shores from one building to another.

My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings, which are hereto annexed and are a part of this specification, in whlch:

Figure 1 is a side elevation of my 1mproved shore connected to a fragmentary portion of false flooring. Fig. 2 is a crosssection taken on the line mw, in Fig. 1. Fig. 3 is a detail view of my improved form of connecting link.

Similar reference numerals refer to similar parts throughout the entire description.

Application fi1ed Ju1y23,1915. Serial No. 11,521.

- formed from fiat steel and the holes 11 and 12, which receive the bolts 8 and 10, can be punched without any skilled labor being necessary for their manufacture, whereas in the case of the form of clevis sometimes employed in the manufacture of adjustable scaffolds, etc., they require a considerable amount of blacksmiths work which is quite expensive, the necessity for which is entirely obviated by my improved construction.

The bolt 10, is mounted in a bushing 13, which-is mounted in the opening near the top of the upright 2, through which the bolt 10, passes. in some cases to fit a cylindrical sleeve 17 i on the bolt 8, to act as a roller when the uprights are being moved in either direction.

Suitable securing means for attaching the upright 1 to the joist 14, which supports the false flooring 15, may be provided. As shown, it comprises a pair of upwardly pro-- j ecting members 16, the upper ends of which are slightly flared as at 18, to permit the easy insertion of the joist. These two members 16, prevent the movement of the upright in one direction, while any 'lateral movement may be prevented by driving a nail through the opening 19, provided for.

that purpose in the upwardly projecting members 16.

It will be obvious from the foregoing description that all of the operative parts of the device are connected or attached thereto so that their loss is effectually prevented, while the form of constructionis such that -no skilled labor is required in the manufacture of the device.

It will be apparent from the foregoing description that any and all heights, which are desired can be obtained by moving the upright 1, along the upright 2, until the bolt 8, enters'the notch 7, in the proper location to attain the height required, and owing to the fact that bolts are used .in the links 9, it is possible to regulate their widths to such nicety, so that while the uprights It may be found desirable,

move freely between them, there is no twisting ofthe two. This result is further assisted by the operation of the metallic U- A shaped bands 3 and 4.

Having described my invention what I regard as new, and desire to secure by Letters Patent is:

An adjustable shore comprising the combination of uprights, one of the uprights being provided with a number of cut out portions along one of its side faces, and having at one end thereof aband, said band adapted to embrace the opposite upright, the op- .posite end of the notched upright having upwardly projecting members arranged on
